      Hello -Did you have a specific question about teaching doubles plus and minus one? This technique has been helpful for my daughter once she was very confident with her doubles facts.

        Not sure what you are asking but teaching doubles means 2+2 or 3+3 ect then adding or subtracting one from the answer. It is used so students will be able to add faster.
